Unfortunately not, but if you defined nullconsole I think no /boot.config is allowed. I'd suggest you try to set hints.sio.1.flags="0x10" and make sure hints.sio.0.flags doesn't exist. This should make the second (not DB-9 connected) serial ports of the 4801 systemconsole. Alternatively you can try setting boot_serial="sio1" in /boot/loader.conf, but I never tried that. Make sure in any case you also have "console=comconsole" in /boot/loader.conf since the soekris bios emulates a simple "VGA"-Console. You can also recompile the loader to tell it what sio (and at what speed) it should use. The following in /etc/make.conf does the trick: BOOT_COMCONSOLE_PORT= 0x2F8 BOOT_COMCONSOLE_SPEED= 115200 For the loader to recompile goto /usr/src/sys/boot and do: make clean && make depend && make && make install Good luck, -Harry > > John > > > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to > "freebsd-questions-unsubscribe@freebsd.org" [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQBCSpIlBylq0S4AzzwRAvvJAJ4mUFDMc8qSGRQytOSmG/Q4BsGoNwCeL9o9 CmR44/3DHv6FO7BpKRZTljs= =bu5U -----END PGP SIGNATURE-----home | help
